Although much less studied, metabolic reprogramming is an obligatory event to enable survival, adaptation, and growth of cancer cells at a distal metastatic site [5,6]. While the typical heterogeneous appearance of metastases is distinct from the homogenous uptake in metabolic bone disease , the appearance of confluent metastatic disease (a superscan) can be quite similar . Afterward, radiotherapy for bone lesions was arranged and the effects were evaluated.

Diagnostic imaging provides important information for staging and response assessment in patients with lymphoma. [1,2] Superscans have been described mostly in metastatic and metabolic bone diseases, and less commonly in myeloproliferative disorders and miscellaneous conditions. Alterations in metabolism fuel the energy and biosynthetic needs of metastases but are also needed to activate cell state switches in cells leading to invasion, migration, colonization, and outgrowth in distant organs. However, the bone scan appearances in metabolic bone disease are often non-specific, and their recognition depends on increased tracer uptake throughout the whole skeleton. Common causes include CKD, primary/secondary hyperparathyroidism, and multiple myeloma.

Background: Metabolic skeletal changes particularly metabolic super scan (MSS) may provide unsuitable soil for survival and growth of tumor cells in cancer breast patients. , 1984). Although the diagnosis is often straightforward, especially as in many cases ther The appearance of the bone scan is consistent with a "metabolic superscan," in this case due to secondary hyperparathyroidism (renal osteodystrophy). A single focal lesion is almost always a cause of dilemma in reporting. In bone metastases, the distribution of intense uptake is in the axial skeleton and proximal portion of long bones, compared to the metabolic bone diseases where May 26, 2009 · Figure: Bone scan image shows diffuse increased bone uptake throughout the skeleton with relative absence of kidney uptake (arrows), consistent with "superscan". g. Metabolic bone disorder such as is seen in renal osteodystrophy should be considered in the differential diagnoses in patients with diffusely increased bone uptake on F-18 FDG PET/CT scan.
